It was two hours after midnight when his lordship slipped down from his bunk. The fire had long since gone out, and the stone chimney was reasonably cool. The climbing of that ample flue presented no difficulty to an athletic young man who in his time had ascended the Matterhorn. The inside of the chimney offered to the amateur sweep walls of rough stone, which projected here and there, forming an effective, if unequal ladder. He attained the top with such ease that he wondered he had remained so long a prisoner. Descending the roof silently, he let himself down to the top of the lean-to which acted as kitchen and supply store, and dropped from that elevation lightly to the ground. It was a night of clear moonlight, and Stranleigh smiled to think how nearly he must represent the popular idea of the devil, covered as he was with soot from head to foot.
He made directly down the hill to the farm house by the stream, and risked a few minutes of time in washing his face in the rapid current. He now took off his boots, the better to enact the part of burglar. The doors of the house, he knew, were never locked. First he secured his favourite magazine rifle and a large quantity of cartridges, then as, after all, he was entitled to the board he paid for, he penetrated softly to the kitchen. Here he secured a couple of loaves of bread and a cooked ham, together with some other things he wanted, including a supply of tobacco, and thus overloaded as he had rarely been in his life before, he stole softly outside, slipped his feet into his boots, and slowly climbed the hill to the silver cavern. Depositing within his goods and chattels, he examined his store carefully to learn whether there was anything more he needed to stand a siege.
Bright as was the moonlight outside, the cavern was pitch dark, so Stranleigh determined on another expedition to the house, and he brought back a bunch of candles and an armful of bedclothes.
"Now for the night's work," he said to himself, and having lit a candle, which he placed at the remote end of the cave, he began picking up stones, and with them building a wall across the mouth of the pit. No Roman wall was ever built with such care, and no Roman wall ever contained within itself such possibilities of wholesale obliteration, because the structure was intersticed with sticks of dynamite, which Stranleigh carried with the most cautious tenderness from the rear to the front of the cavern. When his task was completed the moon had gone down, and the misty, luminous grey of the eastern sky betokened the approach of dawn. The young man was thoroughly tired, and with a sigh of relief he stretched himself out on the bedclothes he had brought from the house.
